Try using this instead of -Xprof: -agentlib:hprof=cpu=samples,depth=6,force=n That'll write a file java.hprof.$pid.txt to the current directory. Look at the end of the file and there'll be a "CPU SAMPLES" section which shows the profiler output. You can search the start of the file for the number in the "trace" column to find a stack trace for that function. If the stack trace isn't long enough, adjust the "depth" option. -- You received this message because you are subscribed to the Google Groups "Clojure" group.
